SONOFF ZBM5 Review – A 3-gang Zigbee Smart Wall Switch tested with eWeLink and Home Assistant

We will be reviewing a smart home device from SONOFF that we recently received right after the New Year, the SONOFF SwitchMan Zigbee Smart Wall (ZBM5). This is SONOFF’s first Zigbee-enabled Smart Wall Switch. In addition to functioning as a smart wall switch, it can also act as a Zigbee Router, making it easier to expand your Zigbee network at home in one shot. One of the key features of the SONOFF ZBM5 is that it can either operate in with-neutral (N) or without-neutral (N) wiring setups. Typically, in the market, we see these as separate models: one for with-neutral and another for without-neutral. This feature adds more flexibility for users, especially those with wiring constraints in their homes. Let’s dive into the details. SONOFF ZBM5 Unboxing Inside the box, you’ll find a user manual, wall plugs, and the switch itself. The model we received has a rectangular shape (120mm) […]

MaTouch SmartKnob Assembled ESP32-based rotary knob with touchscreen display sells for $69

Makerfabs has recently released “MaTouch SmartKnob Assembled” based on the SmartKnob View open-source hardware design but enclosed in a plastic case. As a reminder, the SmartKnob View is an ESP32-S3-based DIY rotary knob built around a BLDC motor. With clever software and engineering, the motor is so configured that it can do software configurable detents, haptic feedback, magnetic encoder, and more. It also has a round LCD touchscreen, and USB-C, and features a convenient 3D enclosure that can also be attached to your wall with some sticky pull tabs. The SmartKnob View was a great concept, but its DIY nature made it difficult for many people to get their hands on one as it was never manufactured in quantities. The MaTouch SmartKnob Assembled solves this issue by building upon the original design and comes fully assembled for immediate use. The original module integrates a 240×240 round LCD and uses an […]

Stackable HAT brings high-resolution 24-bit ADC to Raspberry Pi (Crowdfunding)

24 bit ADC 8 layer Stackable HAT on Raspberry Pi

Sequent Microsystems’ “Eight 24-bit ADC 8-layer Stackable HAT” is a Raspberry Pi expansion board designed for home automation projects. It is compatible with all Raspberry Pi models with a 40-pin GPIO header and features a stackable design that provides scalability for more complex setups. It includes eight independent 24-bit ADC channels, providing ultra-high resolution for measuring small analog signals accurately. It also features programmable gain amplifiers on each input channel for amplifying weak signals and optimizing the ADC’s input range. It is stackable up to eight layers, allowing for up to 64 differential analog inputs. It provides 4A continuous and 5A peak power to the Raspberry Pi via the GPIO header. It sends data via the I2C lines, leaving all other pins free for use. Also, it supports isolated RS485 communication for long-distance connectivity. The 8-layer Stackable HAT for Raspberry Pi is suitable for precision data acquisition applications, including industrial […]

Mekotronics R58-PTZ video surveillance/live streaming embedded computer features a PTZ camera, two HDMI input ports

Mekotronics R58-PTZ embedded computer with pan and tilt camera

I swear it’s not an AI-generated picture of a device, but the Mekotronics R58-PTZ is real and just another unusual Rockchip RK3588 hardware platform from the company that’s an embedded computer with a 3-inch display on the front panel and a PTZ (Pan-Tilt-Zoom) camera placed on top. Mekotronics describes it as a live-streaming box designed for video surveillance, so I assume its main use case is to leverage to built-in 6 TOPS NPU for live streaming with some real-time effect and/or surveillance applications detecting persons, masks, etc… especially it also offers two HDMI inputs for extra cameras. Mekotronics R58-PTZ specifications: SoC – Rockchip RK3588 octa-core processor with CPU – 4x CortexA76 cores @ up to 2.4 GHz, 4x CortexA55 core @ 1.8 GHz GPU – Arm Mali-G610 MP4 GPU with support for OpenGL ES 1.1/2.0/3.2, OpenCL 2.2, Vulkan 1.2 Video decoder – 8Kp60 H.265, VP9, AVS2, 8Kp30 H.264 AVC/MVC, 4Kp60 […]

Adafruit’s PioMatter library adds HUB75 RGB LED Matrix support to the Raspberry Pi 5

The Raspberry Pi 5 brought a more powerful CPU and GPU and faster I/Os compared to the Raspberry Pi 4, as well as some incompatibilities. While the transition from a Raspberry Pi 4 to a Raspberry Pi 5 is usually painless for most applications, Adafruit notes that the ability to drive HUB75 RGB LED matrices was lost on the Raspberry Pi 5 which now relies on the Raspberry Pi RP1 peripheral control to drive GPIOs instead of the Broadcom processor directly controlling them. The company has now addressed that by using the PIO (Programmable I/O) block in the RP1 chip, yes that’s the same PIOs as found in the RP2040 or RP2350 microcontroller, to drive HUB75 RGB LED matrices from the Raspberry Pi 5, and their work can be found on the Adafruit-Blinka-Raspberry-Pi5-Piomatter repository on GitHub. The instructions to install the Adafruit Blinka Raspberry Pi 5 PioMatter library (or just […]

Build a four-wheel RC car with ESP32-CAM board and off-the-shelf parts

ESP32 CAM robot car with off-the-shelf parts

While there are plenty of ESP32-based wireless-controlled robot cars with a built-in camera, like the PiCar-X 2.0 or Zeus Car, it might be more fun and rewarding to build something yourself. That’s exactly what Matt Sroufe did by building his own RC car using off-the-shelf parts and an ESP32-CAM board and writing firmware for it. To get started with the build, you’ll need six main components: A 4-wheel car chassis – $47.49 on AliExpress Electronic speed controller – $5.27 on AliExpress. Matt selected the 30A version with green PCB. Dual-battery holder for about $2 on AliExpress 2x 18650 3.6V cells or 7.4V batteries purchased locally ESP32-CAM board with an external antenna and the 160° FoV camera – About $14 with board, camera, and external antenna. Bluetooth gamepad such as a PS4 controller The total should be around $80 with the batteries assuming you already own a Bluetooth gamepad. You’ll need […]

GEEKOM A6 Review – Part 2: A sub-$500 mid-range AMD Ryzen 7 6800H mini PC tested with Windows 11 Pro (Sponsored)

In the first part of the review, we’ve already checked out the specs, gone through an unboxing and a teardown of the GEEKOM A6 mini PC powered by an AMD Ryzen 7 6800H CPU with up to 32GB DDR5 and a 1TB SSD, before quickly booting the preinstalled Windows 11 Pro. We’ve now had time to test the GEEKOM A6 in detail, so we’ll report our experience with the Ryzen 7 6800H mini PC with Windows 11 Pro. We’ve tested the features, ran benchmarks, evaluated storage and networking performance, stress-tested the device to see how it performs under load, and measured fan noise and power consumption. We’ll also compare it to the previous GEEKOM A5 and A7 mini PCs. [Update: The sponsored tag was added temporarily, as GEEKOM paid for the review to be pinned at the top of the website for one week] Software Overview and Feature Testing Going […]
